Harassment by Vodacom and VVM Debt Collections

In December 2022 i app**** for Vodacom fiber for home use, they couldn't approve me because of my financial status. Early this year i got a call from Vodacom saying that they are sending a technician to come install a open serve fiber , the technician came over to install however they never activated the fiber as i never received the Sim card or any other activation device. i called to inform them that i was still waiting for activation, they never helped me. Around June i got an email saying im owing over R3000 to Vodacom , i emailed them asking what am i owing for ? they said that it was a mistake on their billing side and they will cancell the whole thing and they acknowledged that there was a mistake and they had never activated the fiber for me. to my surprise i got a call from VVM debt collections about vodacom account , i asked them to check with vodacom and stop calling me
